mapping my runs

I’m messing around with a online tool for mapping running routes. I missed my regional long run this morning because, ahem, I overslept. On the MapMyRun website there’s a growing database of routes from which to choose–or to which you may add your own. Helpful enough, for when one grows tired of the same old roads. It would be even better, however, if you could map trail runs as well…I thought maybe one of you readers might find this useful.
(enjoy!)
